Answer:
x= 66
Step-by-step explanation:
if you set up the equation mathematically, it would be x+0.5x=99, because 50% is essentially just 0.5.
so, now that you have the equation, you have to add like terms, so it would be 1x+0.5x=99, and 1+0.5 is 1.5, so youre left with the equation 1.5x=99.
from there, you solve for x by dividing each side by 1.5:
1.5x=99
/1.5 /1.5
x=66
im sorry if this didnt make much sense, but i hope this helped!! :D
